| Abstract: | |
| Rapporten har følgende inndeling: - Beliggenhet. - Vannkraft. - Havn og skipning. - Vei - Malmen (Lagdelt i skifer og med utsvetninger, 40-60 % Fe, 0,2-0,3 % P ubetydelig S). - Areal (Malmens lengde 8 km, bredde vanligvis 5-10 m, untaksvis 25m. Beregnet areal 29.000 kvadrat meter, beregnet masse 34 mill.tonn ned til + 100 m.o.h.) - Brytningskostnader. - Oppredning. - Analyser. |
